In the same way that companies like Toontrack offer additional midi patterns for their drum and EZ keys line, is there any plans to offer something similar for Heavier7? WHIle the patterns it comes with are a great start, it would be cool to have other patterns offering as expansions for the future (i.e. for progressive metal, death metal, etc)

The pattern system in Heavier7Strings includes both MIDI and effect rack preset. So it is more complicated than loops of a drum set, and we cannot offer a lot more new loops. But at least, we will add some additional loops in future updates.
